Make Your Own Cove Molding
Creating Cove Profiles
Three variables determine the profile of cove molding shaped on the tablesaw: the feed angle of the stock over the blade; the blade height; and the blade tilt angle. Different combinations of these three elements create a variety of profiles. (See the drawings.)
A shallow feed angle cuts a compact, elliptical cove [top drawing]. Higher feed angles broaden the curve to a near semi-circular profile.
Final blade height determines the depth of the cove. To see the cove depth cut by a 3/8"-high blade, for example, cover the top drawing just below the 3/8" line (shaded area). The depth of the profile shows above the line (unshaded area).
A blade set 90° to the table cuts a symmetrical cove [top drawing]. Tilting the blade creates asymmetrical coves that "lean" to one side [bottom drawing].
Safety Note: When tilting the blade, feed the stock from the direction the blade tilts. So if your blade tilts to the left, feed the stock from left to right. If it tilts to the right, feed right-to-left.
Experiment to find profiles you like. Save short lengths of your samples and write the feed and blade tilt angles on them for future reference.
